[plug] Here documents

[David Buddrige]

Hi all, 

I want to use a 'here' document to append some text to the end of an 
existing text file.  I have been reading through 'A practical guide to 
Linux' - the section on shell programming but it does not seem to clearly 
explain how to specifically do this. 

My script goes like this: 

cat <<EOF
some text that
I want to add
to the end of my
file
EOF
>> somefile.txt

however this does not seem to work - the 'here' document text is simply 
output to standard-output. 

does anyone know how I would actually add the text in the here document to 
another file as above? 

thanks heaps 

David.
